SPECIFICATION forming part of Letters Patent N o, 667,247, datedFebruary 5, 1901,

Application filed May l2, 1900.

T0 all whom, it may concern.'

Be it known that I, JAMES OBRIEN, a citizen ofthe United States,residingat NewYork, in the State of New York, have in vented a new and usefulImprovement in Water-Gages, of which the following is a specification.

My invention relates to water-gages, and has for its object to produce adevice of this kind which can be easily detached from the valves orcocks projecting from the head of the boiler and which may be providedwith a new glass and quickly returned to its place, thereby avoiding thenecessity of the engineer remaining very long in an inconvenientposition in an overheated atmosphere. With the ordinary gages theengineer is compelled to stand upon a ladder at the head of the boilerin a temperature ranging from 100o to 150o while he removes the brokenglass and puts the new glass in its pla-ce. On board vessels,with theship rolling from side to side, the position is very trying andinsecure, and on locomotives the jar and lurching of the engine fromside to side renders the operation of removing the broken glass aninconvenient and disagreeable operation. When the ordinary valves areleaking steam or Water, the task is rendered the more difficult andobjectionable,and especially Where there is a valvestem projectingentirely across the path of the tube, which must be removed before thenew glass can be inserted. By constructing the stufng-boxes at the endsof the glass removable from the valves they may be removed and the glassinserted and the stuffing-boxes returned to their places much morereadily than the new glass can be inserted in the stationarystuffing-boxes.

My invention consists in the improved construction and novel combinationor arrangement of parts of a water-gage, by means of which thestuffing-boxes are removable, as will be hereinafter more fully setforth.

In the accompanying drawings, in which the same reference-numeralsindicate corresponding parts in each of the views in which they occur,Figure 1 is a perspective View of my improved Water-gage in position,one of the ends being partly broken away to show the parts in section.Fig. 2 is a longitudinal sectional view of the parts of my improved gageseparated. Fig. 3 is a horizontal sec- Serial No. 16,482. @lo modelotional View of one of the valves, and Fig. iis a perspective detail viewof one of the stuiing-boxes.

Referring more particularly to the drawings, 1 and 2 indicate the valvesor cocks of' my improved water-gage, which may be secured to the head ofthe boiler or to the water-col umn in the ordinary manner.

Each of the valves is provided with a longitudinal bore or passage-way 3and a crosspassage 4f near the outer end. The inner portion of thepassage 3 is enlarged to form a seat for the stop-cock 5, by means ofwhich the passage may be closed or opened, as desired. The lower valveis provided with the usual drip-cock 6 for permitting the escape ofsediment or other foreign substances which may collect in the bottom ofthe tube or in the valve.

The outer portion of each of the valves is tapered and provided at itsends with a screwthreaded projection 7. Fitted upon the screwthreadedportion of each of the valves is a stuffing-box S, which is bored out tocorrespond with the taper of the valve and is secured in position bymeans of the nut 9, which fits upon the projection 7. If desired, theinner face of the stuing-boxes may be provided With a projection 10,which engages with the corresponding projection 11 of the valve to holdthe stuffing-box from rotating or turning around when setting up orassembling the parts.

Each of the stufng-boxes is provided with a cross-perforation 12, whichregisters with the passage 4 in the valve when the stuffingbox is inposition, and the drip-cock is preferably secured in the outer end ofthe perforation of the lower box, While the upper end of the perforationof the upper box may be closed by a suitable nut 14, or the box may beprovided with a projection and the crossperforation may be terminated insaid projection. Secured to the stuffing-box so as to face each otherwhen in position are tWo glands 15, which register with thecross-perforation in the valve. These glands are screwed into the stufngportion so as to be adjustable, roo

and are adapted to receive and hold the glass 16 in position. The usualguard-rods 17 are secured at their ends to the plates 18 in the usualmanner.

l are turned so as to shut off the steam and wathe one that has beenbroken.

ter from the top and bottom valves, respectively. The nuts upon theouter ends of the valves are removed and the stuffing-boxes withdrawnfrom the Valves and separated a sufficient distance to permit of the newglass being inserted between the glands in place of The stuffingboXesare then returned to their normal positions and replaced upon the valvesand secured there by replacing the nuts at the outer ends. Should therebe any leakage in the cocks Within the valves, the steam or water willbe deiiected into a vertical direction by the cross-perforations in theends of the valve, and thereby prevented from burning the engineer orinterfering with the manipulation of the parts. In addition to this theescaping steam or water will be thrown into the glass as soon as the studing-boxes are in place, thereby gradually heating it and avoiding thedanger of breaking it by the entrance of the full volume of steam orwater. `rlhe steam or water can be permitted to enter gradually bypartially rotating the cocks in the valves, if desired.

By the use of my improved gage it is evident that the replacing of abroken glass can be performed much more conveniently than with theordinary construction, as the stuiting-boX maybe quickly removed byunscrewing the two ends and the parts can then be cooled gradually orquickly by plunging them into cold water and the glass can be insertedand gradually warmed without danger of breaking.

After the glass has been secured in the glands between thestuiiing-boxes the engineer can return to his position and quicklyreplace the stuffing-boxes upon the ends of the valves, turn the cocksin the valves, and the work is done.

Although I have shown what I consider the most desirable means ofconstructing my improved gage, yet I reserve the right to make suchchanges and alterations therein as will come within the scope of myinvention--as, for instance, the valves may be connected with awater-column, which is connected with the head of the boiler by thevalved pipes 2() in the usual manner, and the drip-cock 6 could beconnected with the valve 2 adjacent to the cock 5 and lead from there tothe ashcette@ pit or other convenient point, as shown in dottedlines inFig. 2.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In a water and steam gage for boilers, the combination, with twovalves, provided with means for closing the same, the outer portion ofeach ot' which is tapered and provided with av screw-threaded projectionand the intermediate portion with a projection, of stufling-boxes forsaid valves, each of which is provided with a projection for engagingwith the projection of the valve, and with means for holding the glass,and nuts upon the outer ends of said valves for holding thestuffing-boxes in position, substantially as described.

2. In a steam and water gage for boilers, the combination, with twovalves, each of which is bored longitudinally and provided near itsouter end with a cross-perforation, of a cock located transversely ofthe bore, of stuing-boxes,on the outer ends of said valves,

'each of which is provided with a transverse perforation to registerwith the cross-perforation of the valves, a gland in each stuffingboX,guard-rods for holding the stuffing-boxes apart, and meansfor holdingthe boxes upon the valves, substantially as described.

3. In a steam and water gage for boilers, the combination, with twovalves, each of which is bored longitudinally and provided with across-perforation at its outer end, the outer end of the valve beingtapered and provided with ascrew-threaded proj ection,a cock seatedacross the longitudinal bore, a stuifing-box on the outer portion ofeach valve, provided with a cross-perforation to register with thecross-perforation of the valve,a dripcock in one end of thecross-perforation of the lower stuffing-box, a screw in the end of thecross-perforation of the upper box, a screwthreaded gland at theopposite end of each of said cross-perforations, and guard rods andplates for'secu ring said stufting-boxes in their relative positions,and a nut upon the screwthreaded projection of each valve, substantiallyas described.

4. In a steam and water gage for boilers, the combination, with twovalves, each of which is perforated longitudinally and transversely andprovided with a bead near its inner end, of a cock arranged transverselyof the longitudinal perforation, a stuffing-box removably secured uponthe outer portion of each valve and provided with a projection forengaging with the bead on the valve, and a glass secured between thestufng-boxes, substantially as described.
